Star Trek TNG - Force of Nature, Data been trying to train his cat Spot to get down from his console with little success, but Geordi remarks that Data's training is coming along.

Spot first appeared in "Data's Day" as a male, long-haired Somali cat. In subsequent appearances, Spot was seen as a more common American short-hair orange tabby, but still as a male. It was only in the seventh season episode "Force of Nature" that Spot was first referred to as she. In "Genesis", she even gave birth.
